MACHINE FOR COATING TILE.

I Application filed September 22, 1913.

To all whom it may concern:

Be it known that I, FRANK B. YINGLING, a citizen of the United States, and resident of Hamilton, Butler county, State of Ohio, have invented certain new and useful Improvements in Machines for Coating Tile, of which the following is a specification.

The present invention relates to an improvement in machines for applying to tile, brick, terracotta, etc., hereinafter for the sake of brevity designated as tile, a coating or glaze in liquid form which, by subsequent burning, is converted into a hard coating or finish.

The particular object'of the invention is to provide a mechanism in which the glaze coating will be delivered to the tile in the form of a freely flowing liquid and to provide means by which the supply of such liquid will. be automatically controlled so that the several tile will be uniformly and properly coated.

In the accompanying drawings, Figure 1 is a plan view of a machine embodying the invention; Fig. 2 is a side elevation; Fig. is a detail elevation of a train of gears employed in the machine; Fig. 3 is an end view; Fig. 4. is a transverse vertical sectional view; F ig. 5 is a detail view on an enlarged scale of the means controlling the opening and closing of the outlet from the glaze receptacle; Figs. 6 and 7 are detail views on an enlarged scale.

F or the sake of clearness several of the features shown in the detail views are emitted from the general views of the machine and many of the parts, are illustrated more or less conventionally.

Referring to the drawings, and particularly to Figs. 1 to 1, it will be seen that the machine includes a main frame or pillar 1 shown as being hollow and provided with an expanded base or foot 2. A tank or reservoir 3 for the liquid glaze is rotatably supported by the frame, being detachably connected with a shaft 4 having thereon a bevel pinion 5 which meshes with a corresponding pinion on a main drive shaft 6, hereinafter more particularly referred to.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Serial No. 791,223.

The machine includes two endless conveyer belts 7, 8, the former being supported by suitable rollers carried on a frame 9 having one end connected with the pillar 1 and further connected by a brace 10 with the expanded foot or base 2. The frame supporting the delivery belt or conveyer 8 is also connected with the pillar 1 and with an upright 11; and, as shown, the rolls about which both of the conveyor belts pass are provided with adjusting means for maintaining the belts in the desired taut condition.

At the upper end of the pillar 1 is mounted a liquid distributer 12, constituting the coating element and which is connected with the tank or reservoir 3 so that as the latter revolves the liquid glaze will be caused to continuously circulate through said distributer and tank. As shown a pipe 13 extends through theupper end of the tank 3 and has its lower end deflected to extend along the bottom of the tank while its upper end is connected, as by a flexible connection 14, with the distributer 12: A drain or return pan 12 is provided to receive surplus liquid from the distributer l2 and discharge the same into the reservoir 3. It will be understood that as the tank 3 is rotated the centrifugal force will act to carry the liquid therein upwardly through the pipe 13 to the distributer 12 and the amount of liquid is maintained in excess of that required for coating the tile to be treated so that it will be constantly agitated and circulated as above described.

The distributer 12 is situated in the vertical plane between the adjacent ends of the conveyers 7 8 and in order to convey the tile across the space separating said conveyers two rolls 15, preferably covered with rubber, are provided. Each of these rolls is provided with a pinion 16 with which engages a pinion 16 on a counter shaft 17 and which shaft is further provided with a pinion 17 that engages with the pin ions 18, 19 mounted on the driving rolls of the conveyers 7, 8.

Above the feed belt 7 is mounted a cleaning brush 20 and the upper end of a duct 21 leading from an exhaust fan 22 is positioned around said brush to carry away any dust that may be removed from the surface of tile passing beneath the brush, such dust being conveyed away to a suitable distance by the outlet pipe 23 of the exhaust fan. As shown, the yoke or bracket 21 in which the cleaning brush 20 is pivotally mounted may be adjusted by means of a screw 24, to compensate for wear of the brush.

The shaft of the brush 20 is connected through means of a belt 25 with the main shaft 6 so that the brush tends to move the tile in the same direction as, but slightly faster than, the belt 7. By thus rotating the brush 20 faster than the belt 7 travels the successive tile in the series on said conveyer will be maintained close together. In order to prevent undue acceleration of the movement of tile beneath the coating devices, a compression roll 26 is provided, said roll being carried by a pivotally supported frame 27. The compression roll 26 is driven by means of gearing 26 and a suitable sprocket 26 and chain, from the shaft of the driving roll of the feed belt 7 and between said compression roll and the coating devices is arranged a roll 28 which, by action of the tile to be treated, as hereinafter to be described, controls the opening and closing of the outlet from the liquid distributer 12. As shown particularly in Figs. 5 and 6 this roll 28 is mounted on a rock shaft 29 to which is attached an arm 30 that is connected by a spring 31 with a stationary abutment on the machine frame. The shaft of the roll 28 is pivotally connected with one end of a sleeve 32, the other end of which is similarly connected with the shaft of a pinion 33 which meshes with the driving pinion 16 of the rolls 15. This connection provides for positively turning the roll 28 while permitting it to have a limited vertical IHOXGIHGIH], which, as hereinafter described, is utilized to control the opening and closing of the outlet from the glaze distributer 12.

The liquid distributer or coating member 12 is provided with a pivotally mounted or swinging gate-like section 3% adapted to turn about a hinge-like support 35 and provided with an upwardly and forwardly extending arm 36. A spring 37 arranged between a bracket 12 on the body of the distributer and the gate 34 normally holds this gate in the position shown in Fig. 5 in which the outlet from the distributer 12 is closed and the extent to which said gate may be turned to open the outlet is adjustably controlled by a screw stop 38.

Mounted in suitable bearings carried by the machine frame are two parallel shafts 39, 40 connected by gears 41 and provided,

" ratchets when disengaged.

respectively, with ratchets 4:2, 43. The shaft 39 is connected by suitable sprockets 39, 39 and chain with a sprocket 39 on the drive shaft of the feed belt 7 and it will be seen that when the machine is operating the shafts 39 and 10 will be continuously rotated in opposite directions.

Loosely supported on the shafts 39, 10 are two pawls 44,45 and a spring 416 coiled about each shaft cooperates with the support for the pawl to normally hold it in the position shown in Fig. 5. The support for the pawl 44 carries a roll 47, which, as said pawl is caused to turn with the shaft 39, will contact with the forward end of the arm 36 and depress the same so as to swing the gate 34: and open the outlet from the glaze distributer 12. Continued movement of the pawl 44. in the same direction brings it into engagement with an adjustable but relatively stationary step 18 which will disengage the pawl from its ratchet 4-2 and thereupon the spring 46 will return the pawl to approximately the position shown in Fig. 5, the end of the pawl contacting with the top side of plunger 52. The pawls a4. and 4-5 are provided with means by which they are held in position out of engagement with the As shown such means comprises spring pressed balls and suitable detents, as conventionally illustrated in Fig. 5.

Means are provided for locking the arm 36 in the position to which it is adjusted by th roll 4:7 on pawl at and maintaining the outlet in the distributer 12 open, such means in the embodiment of the invention illustrated comprising a dog 49 adapted to e11- gage a shoulder 50 on the arm 36 when the latter has been rocked to open said outlet. The parts being thus positioned the arm 36 is released and the outlet from the glaze distributer can be closed by action of the pawl 45. When this pawl is engaged with its ratchet A3 it will be carried forward about the shaft 40 and caused to contact with the dog 49 so as to rock the latter about its pivot and release the shoulder 50 on the arm 36 when the spring 37 will immediately return said arm and the swinging gate 3% to their normal position. As the pawl 45 is carried around the shaft A0 it will contact with an adjustable abutment 51 and be thereby disengaged from the ratchet 43 and returned to its normal position by its coacting spring 46.

Engagement of the pawls i4, 4L5 and their respective ratchets isocontrolled by a shift bar 52 connected with the arm 30 which, as before described, is rocked by the action of a tile passing beneath the roll 28. As a tile is carried by the feed belt 7 beneath the roll 28 the arm 30 will be rocked to move the shifter bar 52 forward and cause it to contact with the depending tail of the pawl 4a and rock into engagement with the ratchet 42 as shown in Fig. 5. This, as previously described, causes the opening of the outlet of the glaze distributer 12 so that the liquid therein will be permitted to flow outwardly onto the tile passing beneath such distributer. So long as there is a tile beneath the roll 28 the parts will be retained in this position, except that, as above noted, the pawl 44 will be disengaged from the ratchet 42 by contact with the abutment 48 and returned to near its normal position or until the lower end of its tail bears upon the upper surface of the shifter bar 52. As soon, however, as the last tile of the series has passed beneath the roll 28, or if there is any appreciable gap or space between two successive tiles in the series, the roll 28 will move downward and, referring to Fig. 5, cause the shifter bar 52 to move to the left and carry the pawl 45 into engagement with the ratchet 13, thus automatically causing a closing of the outlet from the liquid distributer. The parts are so proportioned that the roller 47 will contact with the arm 36 and cause an opening of the liquid distrib uter outlet when the forward end of a tile reaches the central plane of the distributer 12.

The width of the swinging section 34 of the liquid distributer is such that the glaze may be deposited over the full width of the tile passing thereunder and guide rolls 54, 55 are provided for properly directingthe tile. As shown, the roll 55 is connected with a shield or guard 56 so that tile of slightly varying width will be properly coated without allowing the glaze to run down the edge, spring 57 acting to hold the roll 55 in contact with the tile and properly position said shield. Tile necessarily vary slightly in width and length owing to variation in the degree of heat to which they are exposed in different parts of the kiln and the adjustable roller 55 enables the machine to properly coat tile having such slight variation in width. The shield 56 is in the form of a plate fitting close against the inner surface of the bottom of the distributor; and by reference to Figs. 5 and 7 it will be seen that it is adapted to be projected over the outlet from the distributer, or past the plane of the adjacent edge of the swinging section 34, to vary the length of said opening, in accordance with variations in the width of the tiles engaging the roller 55.

In case it is desired to have the coating extend partially over the side edges of a tile the shield 56 will be so adjusted that it does not extend over any portion of the distributer outlet and the dimensions of the swinging closure for the liquid distributer will be such that the opening provided thereby will be slightly greater than the widest tile to be treated. This will permit the glaze to flow over the side edges as well as the upper surface and any undesirable part thereof can be removed by a suitable cutter as is illustrated conventionally at 60 on Fig. 2.

In applying a heavy coating of soft or flowing glazes the coating of detached or separated tile would be so regulated that the glaze would be applied to the tile at the fraction of an inch from the edge and during the subsequent burning operation the glaze would be caused to stand up around it producing a round corner and clean edges. This result, of course, would not be obtained except with glazes which flow during the firing or burning operation.

As indicated in the drawings the liquid distributer 12 is preferably provided with a diaphragm or partition 64 which tends to dam up the glaze in the distributer so that there will always be sufficient ahead to properly fill th slot or discharge opening. This diaphragm does not extend completely to the bottom of the distributer and the glaze therefore passes under as well as over-it.

All of the moving parts are driven from the main shaft 6 provided with suitable driving pulleys. The cleaning brush 20 is driven from this shaft by a belt 25 as previously described and the tile conveyers are connected with the shaft through a belt 61, the blower 22 being similarly driven by a belt 62.

The operation and advantages of the machine will be clearly understood from the drawings in connection with the above description. It will. be seen that a series of tile will be moved successively beneath the discharge opening of the liquid distributor, said discharge opening being automatically opened by the action of the first tile lifting the roll 28 as the forward edge of the tile comes beneath said opening. So long as tile pass beneath the distributor in-such close relation that the roll 28 is maintained in its elevated position, the discharge opening of the liquid distributer will be uncovered, but if two adjacent tile are separated, or as the rear end of the last tile of the series passes beyond the roll 28, the swinging gate 34 will be automatically closed so that there will be no danger of the coating liquid flowing over the rear edge of the tile as it passes under the discharge opening, further the next advancing tile will not be coated on the front edge.
